Maybe it is a problem with the configuration file. Do I need to add something more than <Authenticator>org.apache.cassandra.auth.SimpleAuthenticator</Authenticator> line? It seems that cassandra doesn't found access.properties and passwd.properties files? I have put it in the conf directory, but do I need to put something more in the storage-conf.xml file?

Keyspace name and user names and password are false, it is only for the example.
